HairStrandsCore/Public/HairStrandsInterpolation.h
Reset the interpolation data. This needs to be called prior to ComputeHairStrandsInterpolation and prior to the actual hair simulation in order to insure that: 1) when hair simulation is enabled, the first frame is correct 2) when hair simulation is enabled/disabled (i.e., toggle/change) we reset to deform buffer to rest state)
